I edited this original post. The original can be found at the bottom because I think it's important to know the problem I faced and how customer service went out of their way to help after my original posting.After my initial problems with the first mouse (dysfunctional scroll wheel), customer service offered to send me another. I thought this was great because I enjoyed the mouse except for the issue. When I received the replacement, I was again disappointed to find that my original issue was resolved but there was a new issue that made the mouse pretty much impossible to use comfortably (the left click button was extremely difficult to press. Again, they sent me a new mouse and upgraded the mouse to the top tier. I have been using it for about a week getting accustomed to it. ALL the issues are resolved with this mouse. While I still have to get used to the higher DPI, which is worth getting accustomed to, the mouse works great.Customer service went out of their way to ensure I had a good experience with their product and with their service. These guys are awesome! They stuck this through with me for almost a month as I was testing different mouses they were sending to be certain I gave an accurate review for the product and for everyone to be able to make an informed decision from my experience.ORIGINAL POSTPros:Comfortable, ergonomic, intuitiveCons:Charge capacity, DPI reset and default, MOUSE WHEELThe charge capacity is not what is stated in the description. I get two weeks from a full charge if lucky. The charging cable is portable and it's micro USB, so this issue isn't highly consequential, but inconsistent from the product description of 1 month charge capacity.There are 3 DPI modes which is nice, however the DPI resets constantly. From what I can tell it resets when you turn the mouse off/on and/or when plugging/unplugging the USB receiver. Not a big problem right? You wouldn't think so if you only used mode 2 which is the default. If you want mode 1 or 3 you have to set it every time you turn the mouse on/off or plug/unplug the USB receiver. Doing this multiple times a day when you work remote and in multiple places builds up to a serious inconvenience.The mouse wheel is the biggest issue and insanely frustrating. I want to throw this mouse in the ocean because the mouse wheel does not work properly. It bounces around in whatever direction it likes, not in the direction you are scrolling. At the same time it will either scroll nowhere, back and forth so you still don't go anywhere, or skip 10x the amount you scrolled. I have to use my laptop finger pad to scroll. Why did I buy a mouse??ConclusionThere is no way to work with this mouse. Without a functional scroll wheel it's useless. The pros are great about this mouse but do not outweigh cons. Maybe it's just the one I bought. If the mouse wheel did work, I would probably give this a 3 star because the DPI reset is obnoxious as well but would be manageable for $20. Going to buy a higher quality vertical mouse next time.

This is my first ergonomic mouse. Wish I had tried one way before now. I dont know what my hold up was, maybe because they looked weird and uncomfortable, haha. Well I know what prompted me to try one: my wrist has been bothering me, and it seemed to be made worse with mouse use. I guess all my gaming years have added up.I didnt know which to try. So many! I didnt know what would fit. There are some really small looking ones and some that look bulky, some that are nearly same in appearance as a standard mouse, and some that have a deeper cut out where hand rests. Very confusing. So I just spent some time reading through various reviews of a wide assortment of ergonomical mice.While I think some of it is trial and error for getting the right fit, I think I happened upon a really good fit and feel with my first try. I really have nothing to compare it to, but so far I am really quite pleased.--I dont have small hands, but they aren't exactly big either. Size can be in length and width. I have quite small fingers, but wide palms (3.75"). So typically a size "large" in gloves, but the ends of the fingers always dangle quite a bit. Hope that gives impression going forward with my review:--My hand easily grasps the width of this mouse. Feels very comfortable. My pointer finger just reaches the scroll wheel. I dont need to reach for it; my finger pad sits directly on top of apex of the wheel.--Press of left or right side is easy and comfortable. Plenty of length to accommodate even the smallest of fingers. Yet plenty of spare room for fingers longer than mine.-- Not a loud click, but I can feel the click. I personally find that satisfying. Gentle yet makes me feel my action.--Scrolling is smooth.--No stuttering or jerkiness--Instant connect when I first got this, and no problems since--Impressed with how natural it feels. Didnt realize how much the wrist and forearm twist to use a standard mouse. With this, the mouse and arm are in a natural alignment--Charging is quick and easy. Comes with cord for charging. I charge it directly through use of my laptop. It can be used as a corded mouse with ease. Can store dongle in the mouse if need be. Has on/off switch. When in the ON position, it will go to sleep when computer shuts down (or after x amount of time when not used), and wake up along with computer. Typical for rechargeable mouse. If this is anything like any other rechargeable mouse I have had, it should hold a charge for a very long time.--Haven't used this for gaming yet as I have it for use on my laptop, but may try it out on my gaming PC. If I like it, I will just buy another. I think it will work out. This is just so comfortable and easy to use.Take a little getting used to, yet at same time feels really natural. Good grip, good responsiveness, all around good experience in the short time I have had it. Your experience may vary in terms of fit, but I think the quality is evident. I will update if I have anything else worth sharing :)EDIT/UPDATE: Seriously love this mouse, and this company is great. They are VERY RESPONSIVE and helpful when I inquired about an issue I had. WOW really good customer service. Rare these days, thank you. Truly, 5 STARS ALL AROUND.

This mouse has been a game changer for work and gaming (may not be for super high intensity gaming but have had no major issues with games like dishonored 2, Wolfenstein, and all the simulator games IE electrician sim, tavern master, choo choo charles and more). It has a really long battery life as well, I charge mine maybe twice a month with every day usage. I used to get really bad cramps throughout the day especially working at a computer most of the time so I decided to switch to an ergonomic mouse. Since getting this I have almost no wrist pain. It worked so well I've now bought 4 1 for work 1 for personal and 2 pink ones for my wife for the same reason. I was bummed when one of them stopped charging properly but they came with a 2 year warranty each and it was extremely easy to go through the process to get the replacement. I would not want to switch anytime soon.
